    The embedded man-made disturber rejection algorithm can effectively avoid the electrical interference generated by various household appliances. In addition to allowing general weather enthusiasts to measure local thunderstorm data simply and efficiently, thanks to its compact size and wide detection range, it can also be embedded in various smart wearable devices for an outdoor climber or people who work at heights.This provides early warning of thunderstorms that people can perceive so that people can take precautions a step ahead. The sensor can also be embedded in the indoor protection device inside lightning-sensitive equipment, and automatically trigger these devices to switch to the backup power to isolate the power grid when lightning strikes. At the moment of lightning, the interrupt pin IRQ generates a pulse. This can be used to trigger the shutter to open, helping photographers to accurately capture the exciting moment of lightning.The maximum estimated distance of lightning strike is 40km. Limited by the inherent measurement method and algorithm, the distance estimation resolution is 1~4km, 40 km in 15 steps.Features Lightning detection within 40km in 15 steps Lighting intensity detection Used both indoors or outdoors Embedded man-made disturber rejection algorithm Applications Consumer Weather Station (thunderstorm measurement) Wearable Devices (outdoor thunderstorm early warning) Lightning Photography Specification Input Voltage : 3.3 V - 5.5 V Maximum Detection Range: 40 km Distance Detection Resolution: 1 km - 4 km Intensity Detection Resolution: 21 bits, i.e. 0 ~16777201 I2C Address: Three options 0x03, 0x02, 0x01 Interface: Gravity I2C (logic level: 0-VCC) Dimension: 30 mm x 22 mm For more information, check out the DFRobot Gravity – Lightning Distance Sensor wiki page here.

  •  -20% DFRobot Bluno – Arduino-compatibel Board met Bluetooth 4.0

    DFRobot DFRobot Bluno - Arduino-compatible Board with Bluetooth 4.0

    Bluno is the first of its kind in integrating Bluetooth 4.0 (BLE) module into Arduino Uno, making it an ideal prototyping platform for both software and hardware developers to go BLE. You will be able to develop your own smart bracelet, smart pedometer, and more. Through the low-power Bluetooth 4.0 technology, real-time low energy communication can be made really easy. Bluno integrates a TI CC2540 BT 4.0 chip with the Arduino UNno. It allows wireless programming via BLE, supports Bluetooth HID, AT command to config BLE and you can upgrade BLE firmware easily. Bluno is also compatible with all 'Arduino Uno' pins which means any project made with Uno can directly go wireless! Specifications On-board BLE chip: TI CC2540 Wireless Programming via BLE Support Bluetooth HID Support AT command to config the BLE Transparent communication through Serial Upgrade BLE firmware easily DC Supply: USB Powered or External 7~12 V DC Microcontroller: Atmega328 Bootloader: Arduino Uno ( disconnect any BLE device before uploading a new sketch ) Compatible with the Arduino Uno pin mapping Size: 60 x 53 mm(2.36 x 2.08') Weight: 30 g
